Ambry Genetics

Feb 22, 2023

The c.415C>T (p.R139W) alteration is located in exon 2 (coding exon 1) of the EPN3 gene. This alteration results from a C to T substitution at nucleotide position 415, causing the arginine (R) at amino acid position 139 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
